Pnyx

The Pnyx is a hill in central Athens, Greece, looking down on the ancient agora, the commercial and social center of the ancient city. Beginning as early as 507 BC, the Athenians held their popular assemblies on the hill, and Pericles, Aristides, and Alcibiades spoke to the public from the Pnyx. Its seating capacity was once between 6,000 and 13,000.
